Say what kind of application you want. Point at the substrate. Let the agent build it.
You do not assemble thirty products or read six quickstarts. You write one paragraph, in domain terms, and tell the coding agent where to look. The packages and contracts already agree with each other; the rules the agent reads on its first turn say how they are used; a set of gates it cannot argue with says when it is wrong.
The prompt — all of it
Build a card room on Agentic Primitives. Read https://github.com/agentictrustlabs/agentic-primitives (CLAUDE.md, AGENTS.md, docs/architecture) before you write anything, and use https://github.com/agentictrustlabs/pokernight as the reference application — it is a complete card room on the same substrate. Do not copy it; build mine the same way. People sign in as Smart Agents at their Home (https://www.faithnet.me) — a passkey, not a password. Each player gets a treasury the Home charters on first connect. A buy-in is a grant the player signs with caveats (this table, this token, this ceiling, tonight); the house never holds anyone's key. Two AI players and a coach are A2A agents on the harness. The coach is the texas-holdem/holdem-coach archetype from https://skills.faithnet.io; it reads a player's hands only under a study grant she signed and never sees another seat's cards. Every chip that moves leaves a receipt in the player's vault. Test as the demo people: sign in as alice to play, as bob to custody the coach, as dave to host a club. Deploy the runtime to Cloudflare Workers and the UI to Vercel. Run ap doctor before you tell me it works.
No package names. No tool names. No call sequence. Two repositories, one Home, one registry, three demo people to test as. Everything else the agent fetches — it never has to trust a sentence on this site.
Why this is not just vibe coding
Vibe coding a permission system gets you a permission system that looks right. Here the agent cannot write one: authority is a contract on chain it can only call, the person signs at her own Home, and every protected act leaves a receipt she carries. The generated part is behaviour. The part that must not be probabilistic never was.
